JAMES MANIAS, OF GLENS FALLS, NEW YORK, ASSIGNOR OF ONE-HALF T GUST D. GOLUSES, OF GLENS FALLS, NEW YORK.

AUTOMATIC FUSE.

Application filed June 27, 1924. Serial No. 722,771.

T 0 all whom it may concern:

Be it known that I, JAMES MANIAS, a citizen of Greece, residing at Glens Falls, in the county of Warren and State of New York, have invented new and useful Improvements in Automatic Fuses, of which the following is a specification.

The object of my said invention is the provision of a peculiar and advantageous automatic repeating fuse for use in electrlc connections.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawing, forming part of this specification Figure 1 is an end view of my novel fuse.

Figure 2 is a diametrical section of the fuse on the line 2-2 of Figure Tl.

Figure 3 is a diametrical section takenin the plane indicated by the line 3-3 of Figure 2.

Fi re 4 is an end view of the fuse with the cld sure means removed.

Fi re 5 is a detail perspective the ter mina carrying member of my improvement.

Similar numerals of reference designate corresponding parts in all of the views of the drawing.

Among other elements my novel "fuse com prises a body 1 of insulating material, closed at one end and open at its opposite end and having adjacent to its closed end a threaded portion 2 covered by conductive material 5 and designed to be turned into an appropriate socket (not shown). In the closed end of the body 1 is a screw 4; on which is a nut 5 for securing on the screw one end of a spring terminal 6 that tends to snap or move in the direction indicated by arrow in Fi re 2.

' e terminal carrying member 7 of my im rovement' is formed in one piece of light weight tin or equivalent material, and C0l11 prises a body 8 on which is a ln 9, and terminals 10, the said terminals 10 eing twisted where they join the body 8 so that the terminals will rest at ri ht angles to the body 8, Figures 3 and 5. e body 8 of the member 7 rests over a conductive member 10, and the lug 9 rests back of the said member 10*, while the terminals 10 are arranged in a series at ri ht angles to the spring terminal 6 so that vfiien the terminal 10 at the right of Figure 2 burns out the spring terminal 6 will snap or spring to the next terminal 10 toward the left and so on until all of the several terminals are used in succession. Manifestly when the member 7 is completely burned out it may be expeditiously and easily removed and as readily replaced with a new member 7 Arranged over the open end of the body 1 is a transparent disk 11 of appropriate material, and arranged over the said disk 11 is a closure cap 12 slotted at 13 to display the spring terminal 6 and the several terminals 10, and provided by preference with numerals indicating the several terminals 10. It will also be noticed that the cap 12 is flanged at 14 to detachably secure it on the comparatively large portion of the body 1.

lnterposed between the conductive memher 10 and the conductive covering 3 is a conductor 15 that is contained within the insulating body 1 of the fuse.

As hest shown in Figures 2 and 3 the body 1 is notched at 16 to seat the free ends of the terminals 10 and consequently lateral deflection of the said terminals 10 because of pressure exerted by the spring terminal 1 will be effectively prevented.

t will also he observed that by viewing the fuse through the slot 13 of the cap 12, a party interested can readily ascertain how many of the terminals 10 of the fuse remain intact.

Notwithstanding the practical advantages oi my novel it will be manifest that the same is simple and inexpensive in construction and is well adapted to withstand the usage to which fuses are ordinarily subjected.

l have specifically described the preferred embodiment of my invention in order to impart a definite understanding of the said embodiment in all of its details. I do not desire, however, to be understood as confining myself to the said specific construction inasmuch as my invention is defined by my a pended claims and within the scope of sai claims changes or modifications may be made without involving departure from my invention. 1

Having described my invention, what I claim and desire to secure by Letters-Patent,

is F- 1. A repeating fuse comprising a hollow and closed at its opposite end and having adjacent to its latter end a conductive covering, a s ring terminal connected" to the closed en of the body, a conductive member arranged in the open end of the body and electrically connected by an interior conductor with the said conductive covering, a terminal carrying member resting over the said conductive member and having a 111 back of the same and also having a plurality of s aced terminals intersectin the path of the rec end of the sprin terminal, a transparent disk opposed to t e open end of the body and arranged over the terminal carrying member, and a closure cap arran ed over said disk and secured on the b0 y and having a slot for the display of the terminals.

2. A repeating fuse comprising a hollow body of insulating material open at one end and closed at its opposite 'end and having adjacent to its latter end a conductive covering, a sprin closed end 0 the body, a conductive member arranged in the open end of the body and electrically connected b an interior conductor with the said con uctive covering, a terminal carrying member resting over the said conductive member and having a lug back ofthe same and also having a pluralit of spaced terminals intersectlng the pat of the free end of the spring terminal, a transparent disk opposed to the open end of t e body and arranged over the terminal carrying member, and a closure cap arranged over said disk and secured on the body and having a slot for the display of the terminals; the said body being provided with notches, and the free ends of terminal connected to the the said terminals of the terminal carrying member being disposed in said notches.

In testimony whereof I aflix my signature.

JAMES MANIAS.
